This rewords the doc to have a reasonable summary, adds a little background explaining the opcode behavior and the effect of the function when called multiple times.
Closes ##1154
Done as part of flattening the `util` module. Simply move the `amount`
module out of the `util` module and to the crate root. Justified by the
fact that the `Amount` type is more-or-less a "primitive" bitcoin type.

b80e5aeaab Re-order import statements (Tobin C. Harding)
Pull request description:
Add an API for signing inputs to the `PSBT` struct. This is work based on code in `rust-miniscript` and the API design suggestions below from @sanket1729 and @Kixunil.
Please note, this adds an `unimplemented!` call for taproot inputs. ECDSA signing is complete.
Includes a patch adding the psbt example from https://github.com/rust-bitcoin/rust-bitcoin/pull/940 updated to use this new api. Run `cargo run --example psbt --features=bitcoinconsensus` to test it out.

In preparation for emptying the `internal_macros` module move the
`serde_string_impl` and `serde_struct_human_string_imp` macros to the
`serde_utils` module.
Rationale: `internal_macros` stuff can go over in the `internals` crate
now that we have one. The serde macros could go over there but we have a
`serde_utils` module that holds code for implementing serde traits,
these two macros are exactly that.
`impl_array_newtype` is an internal macro, move it to a new, ever so
meaningfully named, `macros` module.
Use `#[macro_export]`, no other changes to the macro.
Signing a PSBT requires no knowledge other than what we have here in
this library and the PSBT ready to be signed.
This code was pulled out of `rust-miniscript`.
Add a `sign` method to the `PartiallySignedTransaction`.
The import statements in `psbt/mod.rs` are a bit of a mess, re-order
them in an attempt to group like things and separate out things that are
different (e.g. `pub use` from `use`).
Refactor only, no logic changes.

02a2b43b2b Remove Default impl for Target and Work (Tobin C. Harding)
cb9893c4a9 Add Target and Difficulty types (Tobin C. Harding)
Pull request description:
Ugh! 1600 lines of green and 1100 of red - my apologies.
Currently we use the `Uint256` type for proof-of-work calculations. It was observed in #1181 that providing a public 256 bit integer type like this implies that it is a general purpose integer type. We do not want to provide a general purpose integer type (see the 1000 arithmetic functions on stdlib integer types for why not :)
Add two new opaque integer types `Target` and `Work`. These are the inverse of each other, both conceptually and mathematically.
There is a lot of code in this PR, sorry about that. At a high level the PR does:
- Add a `pow` module.
- Put a modified version of `Uint256` in `pow`, making it private.
- Add two new wrapper types `Target` and `Work` that provide a very limited API specific to their use case. In particular there are methods on each to convert to the other.
- Only implement methods that we use on each type.
### Note
During development I got mixed up with the word "difficulty", I have discovered this has a very specific meaning in Bitcoin. Please see rustdocs on the `Target::difficulty` function for explanation of this term. For this reason we use the type `Work` defined as the inverse of target, and reserve "difficulty" for the Bitcoin concept.

Currently we use the `Uint256` type to represent two proof of work
integers, namely target and difficulty (work).
It would be nice to not have a public integer type that is not fully
implemented (i.e., does not implement arithmetic etc as do integer types
in stdlib). Instead of implementing all the stdlib functions we can
instead add two new wrapper types, since these are not general purpose
integers they do not need to implement anything we do not need to use.
- Add a `pow` module.
- Put a modified version of `Uint256` to `pow`.
- Add two new wrapper types `Target` and `Difficulty`.
- Only implement methods that we use on each type.
Note this patch does not remove the original `Uint256`, that will be
done as a separate patch.

98cbdb5a5c Increment lock value (Tobin C. Harding)
Pull request description:
Patch 1 is a docs improvement.
Patch 2 commit log:
When implementing the absolute lock time API we decided on _not_
supporting checking lock satisfaction with another lock, instead we
provided a pattern in the docs for doing so. Fast forward a months and
I, the primary author, then forgot to use the correct pattern when using
the API in `rust-miniscript` - this is a sure sign that the API is too
hard to use. In this time we worked on the relative lock API and came up
with a `is_satisfied_by_lock` method - this is identical to the required
use case in the absolute lock time module.
Add a method on `absolute::LockTime` for checking a lock against another
lock, add rustdoc comment explaining the methods function in filtering
prospective lock time values (how we use it in `rust-miniscript`).

The `user_enum` macro is only used a single time. The macro includes
custom serde logic which can be trivially derived instead.
Remove the `user_enum` macro and just implement `Network` the old
fashioned way. Doing so simplifies the code.
We are attempting to flatten the `util` module; move the `bip32` module
to the crate root out of `util`.
Currently `src/util/` is ignored by the formatter, this patch does not
do formatting, will be done later.
The lock time methods are a source of endless confusion; make an attempt
at improving further the documentation on the two `is_implied_by`
methods (one on absolute lock time and one on relative).
As we just did for `absolute::LockTime` add a method `is_implied_by` and
deprecate `is_satisfied_by_lock`.
Reasoning: it is odd to think of a lock satisfying another lock but it
is clear to see that satisfaction of one lock can imply satisfaction of
another.
Recently we moved a few types from `transaction` to `sighash`, while
doing so I erroneously annotated code with the `deprecated` attribute
hoping it would give downstream users a gentle upgrade experience. It
turns out `deprecated` only works on functions.
During that same work, we re-exported from the crate root a bunch of
types from the `sighash` module that probably should not have been
re-exported. We are currently trying to create a nice clean API surface,
